Weather in Kithnos in June
In Kithnos, June brings early-summer weather that is hot and almost completely dry. Average highs reach 29°C / 85°F, with lows of around 20°C / 68°F. The sea averages about 22°C / 72°F, comfortable for swimming. You're very unlikely to see any rain. The meltemi, the northerly wind of the Aegean, blows on many days and takes the edge off the heat, though it can also whip up dust and rough seas. Kythnos is a low, quiet island in the western Cyclades, within easy reach of Athens. Daylight lasts about 14½ hours, leaving long, light evenings. Pack light, breathable clothes, a sun hat, high-factor sunscreen and sunglasses. When the wind picks up, a light windproof layer is handy for evenings by the water. Heat can build on still days, so drink plenty of water and take breaks in the shade. Get out early and late, and save the hottest hours of the afternoon for the water.
Swimming in Kithnos in June
The sea in Kithnos averages around 22°C / 72°F in June, warm enough to stay in for as long as you like. The sea is swimmable now, but the warmest water comes in July, August and September, when August is at its best. Good spots include Kolona. When the meltemi blows, north-facing beaches get rough, so head for sheltered bays on the south side. Beach bars and sunbeds are open, with more space than in July and August.
Crowds & Prices in Kithnos in June
June is a shoulder month in Kithnos, busy enough to feel lively but well below the summer peak. Prices are noticeably lower than in high summer, and there's more choice of rooms. Go midweek if you can, as weekends bring visitors from Athens. Staying slightly outside the main town usually means better value and more space. Booking a few weeks ahead is usually enough.

Ferries to Kithnos from Piraeus and Lavrio run at full summer frequency in June, but they sell out, so book ahead. It's the full season, so hotels, restaurants, beach bars and excursions are all running. Museums and sites are open on extended summer hours. Opening hours are long, with many tavernas serving until late. Boat trips and excursions run regularly, weather permitting.

Frequently Asked Questions
What time does the sun set in Kithnos in June?
Sunset in Kithnos is at around 8:35 pm at the start of June, around 8:45 pm in mid-June and around 8:45 pm by the end of the month, in Greek local time. The long evenings leave plenty of daylight after the heat of the day.
Is it windy in Kithnos in June?
Sometimes. The meltemi, the northerly summer wind of the Aegean, starts to blow on some days in June, although it's usually less persistent than in July and August. Windy days feel fresher and can make north-facing beaches choppy, while calm days get properly hot. Rain is rare.
Can I visit Kolona beach in June?
Yes, but it's at its busiest in June. Arrive early to find space and parking, and bring shade and water. The sandbar links Kythnos to the islet of Agios Loukas.
Do I need a car on Kithnos in June?
It's the best way to explore. Kithnos is spread out, and buses mainly link the port with the busiest beaches and villages, so a hire car lets you reach quieter corners. In June, book early, as rental cars can sell out.
Is June or July better for visiting Kithnos?
June, for most travelers. It has the longest days, a swimmable sea and a summer atmosphere, with fewer crowds and lower prices than July. July is hotter and busier as school holidays begin, but it's the choice if you want the island in full swing.
